get方法

 @RequestMapping("redirect")
    @ResponseBody
    public JSONObject getRedirectUrl(HttpServletRequest request, String path) throws UnsupportedEncodingException
    {

        if (!path.startsWith("\\d"))

        JSONObject json = null;

        // 1.使用默认的配置的httpclient
        CloseableHttpClient client = HttpClients.createDefault();
        // 2.使用get方法
        HttpGet httpGet = new HttpGet(path);
        CloseableHttpResponse response = null;

        try
        {
            // 3.执行请求，获取响应
            response = client.execute(httpGet);

            // 看请求是否成功，这儿打印的是http状态码
            System.out.println(response.getStatusLine().getStatusCode());
            // 4.获取响应的实体内容，就是我们所要抓取得网页内容
            HttpEntity entity = response.getEntity();

            // 5.将其打印到控制台上面
            // 方法一：使用EntityUtils
            if (entity != null)
            {

        {

        }
